Js inheritance pattern

// Prototype Factory mode 
    function Extend (target, Origin) { 
        target.prototype = the Object.create (origin.prototype); // This method creates an object, modify the parent class and subclass Prototype Prototype independently 
        Object.defineProperty (target .prototype, "constructor" , { 
            value: target, 
            Enumerable: to false 
        }) 
    } 


// object factory mode 
    function the User (Age, name) { 
        this.age = Age; 
        this.name = name; 
    } 

    function Member (Age, name ) { 
        the let instance the Object.create = (User.prototype); 
        User.call (instance, Age, name);  
        instance.pri = function () {
            the console.log ([Age, name]);
        }
        return instance;
    }
    
    var queen = member(11, 'Tom');

 

// multiple inheritance accomplished by mixin 
    the let ADMIN = { 
        prtadmin () { 
            return "ADMIN" ; 
        } 
    } 

    the let User = { 
        the __proto__: ADMIN, // internal mixin inheritance 
        prtuser () { 
            the console.log (super.prtadmin () + "User"); // Super .__ proto__ the this keyword = 
        } 
    }; 

                // the three ways in the method of adding function prototypes 
    
    // Fun.prototype.user = user.prtuser; 
    // Fun.prototype.admin = ADMIN .prtadmin; the method may be a method of adding rename 

    // Object.assign (Fun.prototype, ADMIN, User); using the method changes the original object Object.assign 

    @ Fun.prototype = Object.assign(Fun.prototype, admin, user);
    function Fun() {

    }

    let fun = new Fun();
